EJA438W/EJA438N Diaphragm sealed pressure transmitterDetailed product description：

Sealing diaphragm is used to prevent the medium in the pipeline from directly entering the pressure sensor component of the differential pressure transmitter. It is connected to the transmitter by a capillary tube filled with fluid.

EJA438W and EJA438N diaphragm sealed pressure transmitters are used to measure the pressure of gases, liquids, and vapors, and then convert them into 4-20mADC current signals for output.

EJA438W and EJA438N can also communicate with each other through the BRAN controller, CENTUM CS/μ XL, or HART 275 controller for setting and monitoring purposes.
